Mysterious Water Leak
 
I have a new (4 years old) house on a slab that has a mysterious water leak. Water leaks onto and floods parts of the main floor. After six plumbers and two leak detectors, the source of the leak cannot be found. If the water to the house is turned off, or if the hot water heater is turned off, the flooding stops. The water is all clean water. Has anyone ever seen this type of problem, or have any suggestions on how to find the source of the leak? Thanks.

Something like this is hard to diagnose without being there. Pictures might help though.
I would suspect a failed fitting or pipe. Or a drywall screw in your bottom plate of a wall. Where your pipes are located is hard to say.

A leak in a pipe buried in the slab is not out of the question.

A leak detector might pick up on water oozing out of the pipe using a device similar to a stethoscope.

If a professional leak detector company can't find out where, you may end up having to break open a hole here and there in the slab and expose a pipe (probably a hot water pipe) and determine whether the leak is further on or further back, then dig another hole, etc.

2 things came to me

1- has the water been tested to know if it is ground or treated water?

2- Turn off the water in your house and look at your meter. If there is no water running and the meter is spinning then the leak is in your line.

You mentioned the main water and the hot water, first determine which one it is the main or the hot water and go from there. If it's the hot water maybe you can run new supply and hot water lines above slab.
Got to think about it. Have you hot water bills been high?

Lets see if we can work this out for you
Water comes in your house by going through a meter and then into your house under ground and through a shut off valve.- Turn off this Valve and go look at your meter. If it leaks it is the main water Line.

Then you have a cold line that feeds all of your fixtures and goes to your water heater- If you open the Shut off valve in your house and look at the same meter as noted above it should not be moving. If it is then the leak is inside your house in a Potable water line at which point you just need to figure out what is near that location.

If it is still not spinning then it could be sewer water.... Figure out which fixtures are used when you have water appearing.
